Intertwined magnetic, structural, and electronic transitions in VO
Benjamin A. Frandsen, Yoav Kalcheim, Ilya Valmianski +15
We present a coordinated study of the paramagnetic-to-antiferromagnetic, rhombohedral-to-monoclinic, and metal-to-insulator transitions in thin-film specimens of the classic Mott i…
Probing the quantum phase transition in Mott insulator BaCoS_2 tuned by pressure and Ni-substitution
Z. Guguchia, B. A. Frandsen, D. Santos-Cottin +15
We present a muon spin relaxation study of the Mott transition in BaCoS_2 using two independent control parameters: (i) pressure p to tune the electronic bandwidth and (ii) Ni-subs…
On the Global Geometry of Sphere-Constrained Sparse Blind Deconvolution
Yuqian Zhang, Yenson Lau, Han-Wen Kuo +3
Blind deconvolution is the problem of recovering a convolutional kernel and an activation signal from their convolution $\boldsymbol y = \boldsy…
Dictionary Learning in Fourier Transform Scanning Tunneling Spectroscopy
Sky C. Cheung, John Y. Shin, Yenson Lau +5
Modern high-resolution microscopes, such as the scanning tunneling microscope, are commonly used to study specimens that have dense and aperiodic spatial structure. Extracting mean…
Disentangling superconducting and magnetic orders in NaFe_1-xNi_xAs using muon spin rotation
Sky C. Cheung, Zurab Guguchia, Benjamin A. Frandsen +24
Muon spin rotation and relaxation studies have been performed on a "111" family of iron-based superconductors NaFe_1-xNi_xAs. Static magnetic order was characterized by obtaining t…
Uniaxial pressure effect on the magnetic ordered moment and transition temperatures in BaFeAs (Co, Ni)
David W. Tam, Yu Song, Haoran Man +22
We use neutron diffraction and muon spin relaxation to study the effect of in-plane uniaxial pressure on the antiferromagnetic (AF) orthorhombic phase in BaFeAs and its Co-…
